Canelo is looking to bounce back following a defeat to Dmitry Bivol in May and has not wasted any time in returning to the ring.
The Mexican - regarded as boxing's pound for pound best - was knocked off his perch by the bigger man in Las Vegas but opted to fight GGG rather than a rematch with Bivol next.
They have an iconic rivalry having fought twice in 2017 and 2018 but what numbers did they generate on pay-per-view?

It was the fight fans had demanded for quite some time and the fight took place on Mexican Independence weekend in 2017.
After his win over Julio Cesar Chavez Jr, Canelo confirmed he would face Golovkin at the T-Mobile Arena in Las Vegas.
Despite GGG dominating the majority of the rounds, the scorecards read as a split draw (118-110, 113-115 and 114-114).
According to ESPN, the fight generated $27,059,850 from ticket sales and sold 1.3 million PPVs in America.

The rematch was originally scheduled for May 5, 2018 but Canelo failed a drugs test and was banned from fighting for six months.
T-Mobile Arena was the venue once again for the fight and this time around, it was a much closer fight on the eye.
However, it was Canelo who got the nod via majority decision (114-114, 115-113 and 115-113) to inflict the first defeat of Golovkin's career.
The bout made $23,473,500 from 16,732 tickets sold and on PPV, it delivered 1.1 million sales in America - 200,000 less than the first contest.
